He's OK. Good in small doses otherwise you'll end up wanting to kill him.
He does have a tendency to re-release old effects on "new" DVD's. Some of his stuff is good and some of it is kind of lame.
Revolutionary Coin Magic 2.0 was a pile of crap. And a few of the effects on that DVD were just riddled with "Are you stupid." IE: the one where you clank the coins by the persons ears. I don't care how good you are.. I doubt anybody would let you do that. Not to mention it can and will pretty much give away the entire effect.
